Another word for solutions is heterogeneous or homogeneous mixtures?
What are the two parts of a solution?
Which one gets dissolved?
Why does water dissolve other polar substances?
What word means that something will not dissolve in something else.
Define Saturated, unsaturated, and supersaturated?
On the graph, which variable is the independent variable (it is always on the x axis)
Most solids dissolve better at higher temperatures (which means the line should go up. So what state of matter is NH3 from the graph probably, solid or gas?
How much KClO3 will dissolve in 100 g of water at 30 degrees Celcius?
How much will dissolve in 200 g of water at 30 degrees Celcius?
If you have more than that amount, what would the solution be called? (unsaturated, saturated, or supersaturated?)
If you cool a supersaturated solution does it still keep all the stuff dissolved in it?
Explain in your own words the difference between concentrated and dilute.
T or F 1 mole of HCl in 1 Liter of water would be called a 1 M solution of HCl and 2 moles of HCl in 1 Liter of water would be a 2 M HCl solution?
Will pure water conduct electricity?
Does that make it an electrolyte or a nonelectrolyte?
Why is salt water an electrolyte and sugar water a nonelectrolyte?
What temperature does pure water boil and freeze at?
What will adding salt do to those numbers?
We will be making ice cream on Tuesday. What will we add to the ice to make it cold enough to freeze cream? (p.s. if you want a flavor you can bring stuff to freeze in the ice cream. I will have vanilla and coffee.)
